Having trouble selecting the right pneumatick\u00e9 t\u011bsn\u011bn\u00ed p\u00edstu<\/strong> for your system? You're not alone\u2014there are dozens of profiles, materials, and use cases. But the wrong choice can lead to air leaks, frequent breakdowns, and costly downtime.<\/p>\n

Pneumatick\u00e9 t\u011bsn\u011bn\u00ed p\u00edstu<\/strong> maintain pressure inside air cylinders by sealing the gap between the piston and cylinder wall. A well-chosen seal ensures energy efficiency, long service life, and consistent linear motion.<\/p>\n

In this guide, I\u2019ll walk you through the most common types, materials, and applications of pneumatic piston seals\u2014so you can make the right choice.<\/p>\n

What types of pneumatic piston seals are available?<\/h2>\n

Not all piston seals are created equal. The ideal seal profile depends on your system's load, pressure, and motion speed.<\/p>\n

Here are the four main types you\u2019ll encounter:<\/p>\n\n\n\n\n\n\n\n\n
Typ<\/th>\nPopis<\/th>\nNejlep\u0161\u00ed pou\u017eit\u00ed<\/th>\n<\/tr>\n<\/thead>\n
Symetrick\u00e9 (Z8, COP)<\/td>\nIdentical lips on both sides<\/td>\nReversible stroke cylinders<\/td>\n<\/tr>\n
Asymetrick\u00e9 (Z5, KDN)<\/td>\nOne larger lip on pressure side<\/td>\nStandard single-acting setups<\/td>\n<\/tr>\n

Cel\u00fd p\u00edst (DK, DE)<\/td>\nIntegrated piston + seal combo<\/td>\nCompact pneumatic actuators<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Each seal profile offers specific benefits. For example, symmetrical seals perform well in cylinders that reverse frequently, while composite seals last longer under friction-intensive conditions.<\/p>\n

You can find all of them on our pneumatic seal product page<\/a>.<\/p>\n

Where are pneumatic piston seals used?<\/h2>\n

Pneumatic piston seals are used in almost every machine that relies on compressed air to generate motion. Without them, your cylinder would leak air pressure and lose effectiveness.<\/p>\n
